Nicks made the union official by signing their marriage paper work and presiding over the ceremony during the outdoor event. McCauley instagrammed a photograph of Nicks signing the paperwork commenting, “Here is Stevie Nicks doing my marriage paperwork. It’s a misdemeanor in the state of Arizona if she messes it up. She’s a badass reverend. It was an awesome ceremony. Thank you Stevie! And thank you all for the good wishes!”
